-Creatures you own that aren't on the
battlefield have Split Second.
-Whenever a creature enters the battlefield under
your control you may have it fight target creature
you don't control.
-If a creature you don't control would die as a
result of fighting, instead, until end of turn gain control of that creature, untap it, it gains haste. Sacrifice the creature at the beginning of the
next end step.
